She was willing to answer student questions and provided many practice problems to prepare for the straightforward quizzes and exams. Exams were easier than most of the practice problems. Good curve and no need to read the textbook for her half of the class. Quick to answer email.",

Quizzes similar to practice problems in lecture, and she allows a notecard on the final. She is very nice and is accessible outside of class. Group simulation isn't fun, but not too difficult.

The hard part of the class is not necessarily being able to do questions but rather deeply understanding the underlying concepts. Her final is fairly easy if you paid attention.",
